So I bought a brandnew alienware m17x and it seems to lag when loading areas like trees and house and so on. the game its self doe's not lag only when loading an area ?? what is going on ?? skyrim recommended ultra so I have no clue why i'm lagging. Processor Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz `2.40 GHz with 16.0 GB RAM with NVIDIA GeForce GTX 770M (Windows 7, 64 bit)

- Could be a slow hard drive. Not sure how it's configured, but if youhave a 5400rpm drive it could slow down a little while loading stuff for a new area.- Double check the Optimus settings and make sure the game is using the Nvidia GPU and not the integrated Intel on the CPU.

What is your FPS at? If you are getting a significant amount over 60, skyrim will lag. I have an alienware with a 680m and had the same problem but made a couple changes in the nvidia control panel and everything works fine with everything on ultra except anti aliasing I have at 4.

Try this. Open nvidia control panel and click on manage 3d settings and select skyrim. God to the bottom of the list and force vsync on. Even though I never changed it in the ini, this made a different. Then click adjust image settings with preview then select use my preference emphasizing balance. Keep your skyrim settings at ultra. Give this a try and see what happens. If you have a way to check your FPS, that would be helpful too.

2. Check that the hardware and software for the card is setup correctly for gaming. That the intel graphics isn't being used (as bu-chengshi has mentioned) and that the card is using all the RAM/ VRAM it can.

At the moment Nexus server is having some issues but both this link and the previous do work.

4. Run Skyrim Performance Monitor and Skyrim Vanilla and then Skyrim with the Official hires packs and see if there is any difference with RAM and VRAM usage. Run around a bit covering the same area in each try. There should be a difference between them, if they are the same * then there may be a limit happening with the way your card is setup.

Edit: * the same and both very low.

Other possible solutions.

Lessen your shadow quality.

Frame limiter. Try 32 or 33, don't try 30 as that has been known to cause issues.

if you would like to overclock it all you need to do is install nvidia system tools from their website and done. This is recommended for people who dont know what their doing and is the best idea rather than using 3rd party software like msi afterburner

And how would overclocking do anything to load times? That's all about the hard drive.

Kazuki, when you say "lag" just how much lag are we talking here? That could mean anything from a 10% drop in framerate for two seconds to the game freezing for five seconds every time a new kind of tree gets into view.

I'm surprised you can get Nvidia System Tools to work with a GT 750m, because the site says it only supports up through the 500 series GPUs.
